Basis for Buccal Mucosa Cancer Diagnosis
1.Clinical physical examination
Lesion morphology and consistency are assessed through inspection and palpation, together with evaluation of cervical lymph nodes.
2.Histopathological biopsy
The diagnostic gold standard, confirming tumor type and degree of differentiation; it must be completed before treatment.
3.Computed tomography
Evaluates soft-tissue involvement, invasion of the maxilla/mandible, and cervical lymph node metastasis.
4.Magnetic resonance imaging
Precisely delineates tumor margins and its relationship to critical structures such as the masticatory muscles.
5.Cervical ultrasonography
A preferred noninvasive method for assessing lymph nodes and can guide needle biopsy.
6.Toluidine blue staining
Used as an initial screening tool that can stain dysplastic or malignant cells, but it cannot replace biopsy.
7.Intraoperative frozen-section pathology
Provides real-time assessment of surgical margins to guide complete tumor resection.
8.Multidisciplinary collaborative care
For intermediate to advanced cases, multidisciplinary specialists should jointly develop an optimal comprehensive treatment plan.
9.Daily self-check for buccal mucosa cancer
Monthly self-inspection in the mirror for mucosal color changes and palpation for induration; seek medical attention if abnormalities persist for two weeks.
Conclusion
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that delayed diagnosis of buccal mucosa cancer can have serious consequences. Be alert to oral mucosal abnormalities and undergo timely clinical evaluation, imaging, and pathological biopsy. Accurate staging and pathological subtyping are fundamental prerequisites for individualized treatment, functional preservation, and improved survival.
